Can switching from .com TLD to non .com TLD affect emails even if MX records migrated correctly

I have a high-level question about a customer that switched from a .com TLD to a .fun TLD. They didn’t switch hosting, only their TLD. They’re now having issues with their emails, personal and campaign based, being blocked.

Before I dig in to the technical stuff, I wanted to know if anyone had a similar issue. Before I dig in to MX records and such, I didn’t know if there were known TLD issues with ones like .fun, etc. Sorry if this is a vague question. And I promise I’ve been googling and asking first!

a way to reduce amount of times it checks emails ?

is there a way to a way to reduce the amount of times it checks emails ?

i have changed the “login intervals” from 900 seconds to 1800 seconds,

under “email verification”  “time to wait between 2 logins”

and ticked “per account (else pop3 server)”

i wanted to reduce the amount of times it was logging in to check the emails to increase performance,
as well i was getting loads of errors such as –

“pop3 login failed sock error connection timed out”
&
“pop3 login failed sock error host not found”

but its still bringing loads of messages “skipped email checking”
how to take these off as well to improve performance ?

How to send emails from any address with postfix? [closed]

I’m very familiar with PHP, and I used to use the mail function. I really want to be able to use it on my Raspberry Pi 4 apache2 server. I have php installed, and the mail function always returns true. But it never makes it. It’s not any error with the code or my spam folder because I’m using the same script I used to and there haven’t been any updates to my provider. Anyway, I know I need to install postfix, but I don’t know how. PLEASE READ ON BEFORE GIVING SOME TUTORIAL LINK. Anyway, I need to set it up so that I can send email over the internet AND from any address. Thanks in advance!

Email Verification – Create Emails…

If you click on your project, go to email verification and hit create emails, the list is very outdated. Most don’t work.

The ones that are valid though, it’s not capturing any emails. eg. gmaile.design (No emails are being sent there when actually testing).  Can you fix this @Sven

I was looking for a catchall solution and this doesn’t work sadly.

Can I masschange all admin emails for a multisite instance?

I am managing a multi-site instance of Wp with 300 sites and so I am trying to see if this can be done automatically.

I know individually I can go to each site and change the admin email value in the settings but is there a way to affect all sites? I have tried searching for this and can’t seem to find a post discussing this exact topic.

What to include in generated emails to make them acceptable to email servers?

I need to send some automated emails from a program I’m working on. This is a new feature. I’m generating the emails now, but they get filtered by most of the email servers that I send tests to. Only one server I am using accepts the emails and it allows a lot of spam through. I need to find what headers or authentication or whatever I need to add to make the emails acceptable to major servers.

I’ve tried searching the internet for questions about sending automated emails, but the lead responses are all from companies that are willing to send the emails for me, or that are recommending what the body should look like.

How do I authenticate the email so that it doesn’t get flagged or filtered as spam?

Also, does length play any part in typical spams filters (i.e. are short emails more likely to be filtered)?

Should big companies publicly list their legit emails and links?

I’ve been going through a hassle with a big mobile company about if I should click into a link in an email that I think is from them. The email and the link inside is not obviously from the company, as the domains do not match up to the providers domain, or alternate domains. It seems through discussion on the company forum that it’s not clear that this email is legit. This has been a confusing situation.

Should large companies have a security standards page, wherein they list all legit emails and domains that belong or are associated with them? For someone like me who checks the sender email and the domain of the links within it, I want to know who they are. If the company listed them on their website I would feel instantly safe. But instead I’ve wasted hours trying to resolve this situation without an answer yet.

My question – does such a scheme exist to list legit emails/domains on company websites? If not, why? If so, where?

How to perfectly wipe a duplicated project (statistics & URLs & emails) in GSA SER ?

I wanted to duplicate an already used project and couldn’t find out how to clear everything in the new copy. To delete the URL cache, the URL history and the accounts is not enough. The statistics (Submitted/Verified) for example keep the data from the original project. I’m sure there is some more data kept in the background too. Who can help please?
